CVE-2020-23374: 
noneCms vulnerability analysis and mitigation

Cross-site scripting (XSS) vulnerability identified as CVE-2020-23374 affects noneCMS v1.3.0. The vulnerability exists in the admin/article/add.html endpoint, allowing remote authenticated attackers to inject arbitrary web script or HTML through the name parameter (MITRE CVE).

The vulnerability is a Cross-site Scripting (XSS) issue that affects the admin interface of noneCMS version 1.3.0. Specifically, the vulnerability is present in the admin/article/add.html path where the name parameter is not properly sanitized, allowing for the injection of malicious web scripts or HTML content (MITRE CVE).

When successfully exploited, this vulnerability allows authenticated attackers to inject and execute arbitrary web scripts or HTML in the context of other users' browsers who access the affected admin page. This could lead to theft of sensitive data, session hijacking, or other malicious actions performed in the context of the authenticated admin user (MITRE CVE).

Users should upgrade to a version of noneCMS newer than v1.3.0 if available. If upgrading is not immediately possible, implementing proper input validation and output encoding for the name parameter in the admin/article/add.html endpoint can help mitigate the vulnerability (MITRE CVE).
